Known for its many uses - Unica has been named as the one solution for anterior restorations.

A simple and ideal matrix, Unica is the ideal tool for class III, IV, V, direct stratification composite veneers, and shape modifications.

In this clinical case, Dr. Carlos Fernández Villares illustrates how Unica's contoured profile allows for an anatomic restoration and an aesthetic end result.

Case Report

A young girl with two ceramic veneers in the laterals came to our attention to improve her aesthetics. We proposed to substitute the veneers with new composite ones. The creation of composite veneers not only satisfied the patient’s desire to know the final anatomy before the completion of the treatment but provided an easier solution to modify than using ceramic veneers.

The following case study shows the step-by-step procedure of the composite veneer built up using Polydentia’s Unica anterior matrix.

First Steps

1. Pre-operative view showing two ceramic veneers on laterals 12 and 22. 

2. Isolation of the operatory field  

3. Old ceramic veneers have been removed first. Adjacent teeth have been protected using a metal matrix before proceeding to sandblasting the surfaces with aluminum oxide and water. Sandblasting allow us to eliminate some remains of the previous restoration and pave the way for the adhesive procedure.

4. Adhesive procedure: a universal system adhesive with a selective etching approach has been used to increase the bonding forces in the enamel
